Turbulence Modeling via Data Assimilation and Machine Learning for Separated Flows over Airfoils

AIAA Journal, 2023
Reynolds-averaged Navier–Stokes (RANS) models, which are known for their efficiency and robustness, are widely used in engineering applications. However, RANS models do not provide satisfactory predictive accuracy in many engineering-relevant flows with ...
